I have been facing this problem for about 9 hours. When I check browser's network tab. There is an error with status code 409 "status" : "409", "code" : "ENTITY_ERROR.RELATIONSHIP.INVALID", "title" : "The provided entity includes a relationship with an invalid value", "detail" : "You cannot create a new version of the App in the current state.", "source" : { "pointer" : "/data/relationships/app" }
